IMPORTANT
The wheel nuts should be tightened to
110 Nm. Overtightening can damage the
nuts and the bolts.
Steel rims – standard wheel nuts (1)
Steel rims are normally mounted with the
standard wheel nuts, but the bulge acorn vari-
ety may also be used.
WARNING
Never use standard nuts for aluminium rims.
The wheel could come loose.
Aluminium rims – bulge acorn wheel nuts
(2)
Only use the bulge acorn variety of nuts with
aluminium rims. These differ markedly from
other nut types as they have a rotating conical
washer.
NOTE
These nuts may also be used with steel rims.
Locking wheel nuts
Locking wheel nuts can be used on both alu-
minium and steel rims. If steel rims with locking
wheel nuts are used in combination with wheel
covers, the locking wheel nut should be moun-
ted on the bolt nearest the air valve. Otherwise
the wheel cover cannot be fitted to the rim.
Spare wheel Temporary Spare*
The spare wheel is only intended to be used for
the short time it takes to get the normal wheel
replaced or repaired. Replace the spare wheel
with a normal wheel as soon as possible. The
car's handling may be altered by the use of the
spare wheel.
Never drive faster than 80 km/h with a spare
wheel on the car.
IMPORTANT
The car must never be driven fitted with
more than one "Temporary Spare" wheel.
